INSTALLATION AND OPERATION MANUAL

DIP Switches

The CNGE2+2SMS's dip switches configure switch features. The DIP Switches are numbered from
left to right when viewing the side of the Switch with the backplate on the bottom and the power
connections on the left. If "Web Management Enable" is selected in the management software
under System Settings, the DIP switch settings will be overridden by any settings made in the
browser interface.
Switch Function Listing
The switch functions may be set individually or may be combined in the following order to perform
enhanced functions above the individual operation. The table below describes the operation of the
switch functions. This same table is also available in the help menu of the system webpage.
